Preface
In 2002, sales of herbs/botanical supplements increased to an estimated $4.3 billion per year
From 2001 to 2003, herbal products for women increased by approximately 25%
In 2005, a secondary analysis of the complementary and alternative medicine (CAM) supplement to the 2002 National Health Interview Survey (NHIS)2,3 estimated that more than 38 million Americans use herbs and dietary supplements. More recent estimates have placed this number as high as 60 million.

Chapter 1 Introduction to Pharmacology of TCM
1.Concept of Pharmacology of TCMPharmacology of TCM is the study of the actions, usage, mechanism
and adverse effects of TCM (includes acupuncture, herbs, qigong, tui-na, TCM theory, etc.) with modern scientific methods.
2. Tasks of Pharmacology of TCM
(1) Research the functions of TCM
(2) Research how TCM acts on the human body
(3) Research why TCM has those functions
In this course, we will only be studying the herbal pharmacology of TCM. (HTCM)
3. History and Development of HTCM4. Research Methodology of HTCM
(1) To analyze the chemical structures of TCM herbs, and to purify the active structures or even to synthesize them. Then, to put them into clinical trials methodically after understanding their pharmacology and toxicology
(2) To research HTCM according to the theory of TCM i. To explain the crux of TCM according to formula theory ii. To research TCM syndromes through animal experiments. iii. To research the behaviors, characteristics and properties of
the herbs in complex TCM formulas. iv. To help discover new patent herbs or formulas
Research Methodology of HTCM
in vitro studies
animal studies
clinical studies
5 Tastes of HTCM (1) Pungent Herbs i. Herbs that relieve exterior syndrome: They mainly contain volatile oils that o Promote sweating o Improve microcirculation o Are anti-bacterial o Are anti-viral exterior syndrome o Stimulate appetite o Relax spasm o Relieve pain
ii. Herbs that regulate qi:
They mainly contain volatile oils that o Regulate digestive function o Activate smooth muscle o Help secretion of digestive juice o Stimulate appetite o Relax spasm o Relieve pain
(2) Sweet HerbsMost of them are rich in nutrition (amino acid, sugar, glycoside).
Some of them can improve immune function.(3) Bitter HerbsThey are rich in alkaloid and glycoside that are anti-
bacterial, anti-viral and anti-inflammatory (Huang Lian has
berberine).(4) Sour HerbsThey are rich in tannic acid and organic acids that have
strong astringent action.(5) Salty HerbsThey contain iodine and inorganic salts.
6. Acute Toxic Test of HerbsLethal Dose 50 or LD 50 is determined and defined as
that dose of a drug which kills 50%of the animals to which it is administered. The concept of LD50 suggests that if a whole population (rather than just an experimental sample) were exposed to this dose (which is actually the median lethal dose), 50% of the population would live and 50% would die.
7. Long Term Toxic Test of Herbs – about half a
yeare.g. Chuan Wu and Ma Qian Zi have toxic effect on the
heart, and Mu Tong, and Guang Fang Ji have toxic effect on the kidney.
Chapter 2 Herbs that Relieve Exterior Syndromes

[Indications]
1. Bronchial asthma
2. Stuffy nose
3. Low blood pressure
4. Urticaria.
[Side Effects]1. Lead to bleeding of eyes
2. ON nervous and cardiac system(eg:MDMA, CRYSTAL METH 、 CRYSTAL 、 SHABU 、 GLASS 、 BASE. Eg:Nervousness, anxiety, palpitations, headaches, nausea, hypertension, seizures, strokes, myocardial infarction, hyperthermia, and death have been reported. )
3. Lead to restlessness, insomnia
[Interaction]
1. avoid with medication that are for lowing blood pressure 2. avoid with medication that are for promoting sweats
Adverse Effects
1.Nervousness, anxiety, palpitations, headaches, nausea, hypertension, seizures, strokes, myocardial infarction, hyperthermia, and death have been reported.
2.Myocardial ischemia and infarction, dysrhythmias, and uncontrolled hypertension have been reported following consumption of ephedra
3.This may be caused by increased oxygen demand of the myocardium in persons with pre-existing arteriosclerotic heart disease who ingest this substance
4.Reports of cerebral vascular ischemia, intracranial hemorrhage, and central nervous system vasculitis have all been reported in association with the ingestion of ephedra. Seizures have also been associated with its use. Ephedra extracts have been shown to be toxic to specific neuronal cell lines.
5.Acute psychosis has been linked with ephedra usage.
Gui Zhi (Cinnamon twig, cinnamomun)
[Main Components]
1. cinnamic aldehyde
2. cinnamic acid
3. phenylpropyl acetate (few)
[Effects & HTCM]
1. Dilating blood vessels to promote sweating
Cinnamic aldehyde can help blood flow to skin, especially with ephedra
2. Reducing fever & stopping pain
This action is related to promoting sweating.
It can increase the ability of enduring pain(pain threshold).
3. Tranquilizing: can anti- convulsion.
4. Being anti-inflammatory and anti-allergic
5. Being anti-bacterial (staphylococcus aureus, pneumococcus) and anti-viral (influenza virus)
It can be anti-staphylococcus aureus, anti-TB. It can be anti-ECHO11 (V.). [Indications] [Side Effects]
Chai Hu (Bupleurum Root)
It is bitter in flavor, slightly cold in nature, and acts on liver and gallbladder
[Main Components]
1. Saiko-side a, b, c and d
2. a-spinastral
3. Volatile oil
4. Fatty acid
[Effects & HTCM]
1. Abate fever. The dosage size of bupleurum root is directly proportional to its effectiveness in lowering
fevers due to typhoid bacillus and colibacillus. Saiko-side and volatile oil have the fever abating effect.
2.Tranquilize, has analgesic effect, and stop cough. The saiko-side has this effect but is less potent than codeine.
3.Promote immune function. It can strengthen the action of Kupffer’s cell and NK cell.
4.Protect liver, cholagogize (benefiting the gallbladder) and lower cholesterol. The saiko-side has this effect. Bupleurum root prepared with vinegar is more effective in lowering cholesterol (especially for triglyceride)
5.Treat digestive ulcer. The saiko-side can prevent the mucosa of the stomach from being impaired by acid and alcohol.

[Indications] TCM1. Alternate fever and chills2. Hypochondriac pain3. Irregular menstruation4. Prolapse of uterus Pharmacology1. Respiratory infection.2. Cough due to different lung diseases3. Viral Hepatitis4. Hypercholesterolemia [Side Effects]1. Excessive intake would lead to sleepiness, poor appetite,
and abdominal distention. 2. Injection may lead to allergic reaction.
Interactions Interactions with Drugs (1)Bupleurum may increase the risk of bleeding when taken with drugs that
increase the risk of bleeding. Some examples include aspirin, anticoagulants ("blood thinners")
such as warfarin(Coumadin®) or heparin, anti-platelet drugs such as clopidogrel (Plavix®), and non-steroidal, anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
(2)Bupleurum may stimulate the adrenals and may decrease the effects of antihypertensives(drugs for high blood pressure). Patients taking blood pressure medications, including beta-blockers or ACE inhibitors, should use cautiously.
(3)Although not well-studied in humans, bupleurum may reduce cholesterol levels. Caution is advised in patients taking cholesterol-lowering agents.
(4))Bupleurum may increase the amount of drowsiness caused by some drugs. Examples include benzodiazepines such as lorazepam (Ativan®) or diazepam (Valium®), barbiturates such as phenobarbital, narcotics such as codeine, some antidepressants, and alcohol.
Ge Gen (Kudzu)
Kudzu originated in China and was brought to the United States from Japan in the late 1800s. It is distributed throughout much of the eastern United States and is most common in the southern part of the continent.
Kudzu has traditionally been used in China to treat alcoholism, diabetes (high blood sugar), gastroenteritis (inflamed stomach or intestine), and deafness.
Evidence suggests kudzu may improve signs and symptoms of unstable angina (chest pain), improve insulin resistance, and have a positive effect on cognitive function in postmenopausal women. However, most studies have suffered from methodological weaknesses and small sample sizes.
Chinese healers have used kudzu to treat high blood pressure and chest pain and to minimize alcohol cravings. Research indicates that puerarin (a constituent of kudzu) may increase blood flow to the heart and brain which helps explain certain traditional uses.
Ge Gen (Kudzu, pueraria) [Main Components]1. Daidzin2. Daidzein3. Puerarin [Effects & HTCM]1. Reducing fever.2. Effects on circulatory system (1) Puerarin can reduce blood pressure (2) Promote the circulation of the brain (3) Dilate the coronary vessels. It can relax the spasm of
coronary vessels. Good for coronary heart diseases. (4) Promote heart function.
3. Relax the smooth muscles of the intestines
4. Other actions: (1) It can reduce the function of platelets (2) It can lower blood sugar [Indications]
1. Hypertension
2. Coronary Heart Diseases
3. Migraines [Side Effects]
1. Side Effects and Warnings Currently, there are no side effects reported of kudzu treatment when taken by
mouth. Intravenous puerarin has caused intravascular hemolysis (destruction of red blood cells). Intraperitoneal administration of puerarin or crude extracts of Pueraria lobata caused hypothermia (low body temperature).
In theory, intraperitoneal administration of puerarin or crude extracts of Pueraria lobata may cause hypothermia. Kudzu root may also cause weight loss, although this has not been well studied in humans.
2. Interaction: Antidiabetics: Anticoagulant & antiplatelet drug:
3. Pregnancy & BreastfeedingKudzu is not recommended in pregnant or breastfeeding women due to a lack of
available scientific evidence.

Berberine Activity
Antimicrobial Cardiovascular effects Anti-inflammatory effect others
Antimicrobial Effects
Bacterial Diarrhea Intestinal Parasites Ocular infections Et al
Bacterial Diarrhea
Direct antibacterial effects Inhibiting the intestinal secreatory response
cause by V. cholerae, and E. coli Also block the adherence of bacterial to
erythrocytes and epithelial cells Clinical studies showed that a single dose of
berberine sulfate 200-400mg orally significantly reduced liquid diarrhea stool compare to control without side effects (Rabbani et al 1987; 1996)
Dosage and toxicity
The LD 50 of berberin in mice 25mg/kg iv. ; while no gross toxic effects in dog at 45 mg/kg
High doses may result in lowered BP, dyspnea, flu-like symptoms, GI discomfort and cardiac damage
The therapeutic dose of berberine as oral supplement is typically 200 mg two or three times daily
pharmacokinetics Sulfate-conjugated metabolites of berberine were
identified after oral administration at 0.9 g per day, 3 days, in healthy volunteers' urine.
Little berberine was recovered in urine compared with its metabolites (Pan et al., 2002 ).
Berberine seems to be extensively metabolized in the body.
there is little information available on pharmacokinetics following administration. .
Huang qin
Scutellaria baicalensis Georgi Has antioxidant, antiviral, antibacterial,
antiinflammatory, antiallergic, and sedative properties.
Major components are flavonoids, such as baicalin, baicalein, wogonin et al, dominated by baicalin, which makes up 12-17% of the root
Baicalein
Baicalein, one of the major flavonoids contained in the dried roots, possesses a multitude of pharmacological activities.
Baicalein and dosage In China, baicalin is prepared in injection form for rapid action.
The dosage is 60-120 mg of baicalin intramuscularly, 1-2 times per day; or a daily IV drip containing 500-1200 mg may be utilized for more severe diseases.
Orally, Huangqin is given in decoction, with dosages of about 6-12 grams per day, yielding baicalin in amounts of 1-2 grams.
Baicalein tablets, and highly purified baicalein extracts in powder form (with 95% flavonoid content) are used at doses of 1-2 grams per day. These treatments are usually for acute syndromes; lower doses of baicalin in complex formulas would be utilized for prolonged therapy.
Pharmacokinetics
Baicalin orally, slow absorbed, take 7-16 hrs to the peak concentration
im, quick absorb, takes 0.4 hrs to peak concentration, half time about 0.6 hrs
Kidney excretion
Baicalin activity
Inhibition of infections (especially respiratory tract viral infections).
Anti-inflammatory (e.g., for asthma or atopic dermatitis) Inhibition of cancer cell proliferation; Protecting bone marrow and promoting hemopoiesis during
cancer therapies and protecting the intestines from adverse chemotherapy effects;
Blood pressure lowering Sedative, Bile-secreting, Neuroprotective and hepatoprotective
Inhibition of infections
Antibacterial and antiviral agents. They are effective against staphylococci, cholera, dysentery, pneumococci and influenza virus.
especially respiratory tract viral infections anti hepatitis B virus. Both Huangqin and
isolated baicalin are widely used in China for treatment of viral hepatitis and are believed to have potent protective action against liver fibrosis caused by viral activity.
Formula
Shuanghuanglian (SHL for short) is a modern formula
extracts of three herbs: lonicera (shuanghua, often called jinyinhua), scute (huangqin), and forsythia (lianqiao). (2:1:1)
treatment of respiratory tract infections, cases of viral myocarditis et al.
Anti-inflammatory
Cyclooxygenase (COX) and 5-lipoxygenase (5-LOX) inhibition in a dose-dependent manner
Prostaglandin E2 generation was inhibited
for asthma or atopic dermatitis
Huang qin
anti - histamine effect: huang qin possesses antihistamine effect. It can inhibit edema of rats model.
anti allergenic effect: alcohol extract of huang qin inhibits acute asthma attack and allergenic eczema.
Baicalein inhibits permeability of capillaries and anti acetylcholine and anti anaphylaxis effects.
Anti-tumor
Inhibition of cancer cell proliferation Induction of apoptosis by baicalin was accompanied with
the marginal generation of intracellular reactive oxygen species (ROS), the increase of the cytochrome c, and the disruption of mitochondrial transmembrane potential prior to the activation of caspase-3.
On the other hand, baicalin showed little toxic effect on peripheral blood mononuclear cells from healthy volunteers.
These results indicate that baicalin acts as a prooxidant and induces apoptosis via mitochondrial pathway.
Antioxidants
Antioxidants play a key role in cardiovascular disease, cancer, cataract formation, the aging process, inflammatory diseases, and a whole variety of neurological disorders.
Inflammation and cancer
Chronic infection and inflammation contribute to about 25% of all cancer cases worldwide
Anti-tumor
Flavones (chrysin, baicalein, and galangin), flavanones (naringenin) and isoflavones (genistein, biochanin A) inhibit the activity of aromatase (CYP19), thus decreasing estrogen biosynthesis and producing antiestrogenic effects, important in breast and prostate cancers.
Others
Protecting bone marrow and promoting hemopoiesis during cancer therapies and protecting the intestines from adverse chemotherapy effects;
lowers blood pressure
Plant-derived baicalein and its analogs are used to treat arteriosclerosis and hypertension.
In vivo hypotensive effect may be partly attributed to its inhibition of biosynthesis and release of arachidonic acid-derived vasoconstrictor products.
Baicalein may reduce vasoconstricting sensitivity to receptor-dependent agonists such as noradrenaline, phenylephrine.
inhibition of the endothelial nitric oxide-dependent mechanism.
anti-thrombotic
Baicalein inhibits thrombin-induced production of plasminogen activator inhibitor-1, and interleukin-1beta- and tumor necrosis factor-alpha-induced adhesion molecule expression in cultured human umbilical vein endothelial cells.
Anti-ischemia-reperfusion injury in cardiomyocytes..
The free radical scavenging capacity When flavonoids were administered during
ischemia/reperfusion, baicalein significantly reduced cell death.
Anti-atherosclerosis
Atherosclerosis is a multiple factors disease, in which the main roles play oxidant stress, endothelium dysfunction and disorders of hemostasis
Hangqin in the nearest future could be used in the primary and secondary prevention of atherosclerosis
Mechanism: anti-oxidant, increase HDL and reduces TG et al.

II. WHO RECOMMENDATIONS ON MALARIA TREATMENT
antimalarial medicines, WHO recommends that all countries experiencing resistance to conventional monotherapies, such as chloroquine, amodiaquine or sulfadoxine yrimethamine, should use combination therapies, preferably those containing artemisinin derivatives (ACTs artemisinin-based combination therapies) for falciparum malaria (3, 4).
Forms of artemisinin, developed in China from the wormwood plant, have become the leading treatment — but only when used together with older medications. This artemisinin combination therapy, known as ACT is 95 percent effective in curing malaria.
1. Antimalarial: The mechanism is associated with the blocked utilization of host erythrocyte protein by the plasmodium, causing starvation and death.
2. Antibiotic: It can inhibit Staphylococcus aureus, Neisserria catarrhalis.
3. Antihypertensive: It can decrease ht rate, inhibite contraction of the cardic muscle.
4. Antipyretic:
5. Cholagogic: it can increase the production & excretion of bile in rates.
WHO currently recommends the following combination therapies (in alphabetical order):
1. artemether/lumefantrine 2. artesunate plus amodiaquine (In areas where the cure rate of
amodiaquine monotherapy is greater than 80%) 3. artesunate plus mefloquine (Insufficient safety data to
recommend its use in Africa) 4. artesunate plus sulfadoxine/pyrimethamine (In areas where the
cure rate of sulfadoxine/pyrimethamine is greater than 80%) Note: Amodiaquine plus sulfadoxinepyrimethamine may be
considered as an interim option where ACTs cannot be made available, provided that efficacy of both is high.

Stimulant. The fruit is antibacterial, carminative, diuretic, odontalgic, stimulant,
and stomachic[4, 21, 61, 176, 240]. It is taken internally in the treatment of abdominal pain, digestive disturbances and complaints such as lumbago[176, 238]. It is often included in remedies for digestive disturbances and cough mixtures, in part at least for its pleasant aniseed flavour[238]. An effective remedy for various digestive upsets, including colic, it can be safely given to children[254]. The fruit is also often chewed in small quantities after meals in order to promote digestion and to sweeten the breath[4, 238]. The fruit has an antibacterial affect similar to penicillin[176]. The fruit is harvested unripe when used for chewing, the ripe fruits being used to extract essential oil and are dried for use in decoctions and powders[238]. A homeopathic remedy is prepared from the seed[4].

Indirubin is the active ingredient of Danggui Longhui Wan, a mixture of plants that is used in traditional Chinese medicine to treat chronic diseases. Here we identify indirubin and its analogues as potent inhibitors of cyclin-dependent kinases (CDKs). The crystal structure of CDK2 in complex with indirubin derivatives shows that indirubin interacts with the kinase's ATP-binding site through van der Waals interactions and three hydrogen bonds. Indirubin-3'-monoxime inhibits the proliferation of a large range of cells, mainly through arresting the cells in the G2/M phase of the cell cycle. These results have implications for therapeutic optimization of indigoids.

Hemostatic effect Cardiovascular effect Protect the liver Anti-inflammatory effects Anti-carcinogenic effects on some forms of
cancer.
Sanqi
Contains many chemical constituents. Saponins derivatives (PNS), which is a
mixture of more than 20 types of saponins, four or five of them are considered as the principle active ones Notoginenoside R1, ginsenoside Rg1, Rd, Re
and Rb1 (75-80% total PNS) Flavonoids et al.
Pharmacokinetics
Oral administration, most Saponins derivatives (powder) tested in rats, reached peak concentration in plasma rapidly within about 0.75 h - hint their absorption were quick.
Maximum concentration in rat plasma were low indicated that it may be poorly absorbed and /
or extensive metabolized (intestinal microflora, liver) ….
Pharmacokinetics
Half time was changed from 1 to 20 hrs in rat plasma after oral administration of the constituents
Iv in rats, most constituents were cleared quickly except a couple of PNS the pharmacokinetic profile diversities of these
constituents are probably one of the mechanisms of the multiple pharmacology activities
San-qi
Many preparation were used in clinic in China (tablet, drop pill and injection)
Xuesaitong injection is consisted with only PNS Very difficult to evaluate the pharmacokinetic
profile Pharmacokinetics parameters are different
from individual compounds

Effects on brain
Protect ischaemic brain damage Decrease brain edema, infarct size and
neuron damage Inhibit uptake calcium by neuron cells
isolated from rats Protect cultured rat cortical neuron from
glutamate neurotoxicity
Ischemic cascade1. Lack of oxygen causes the neuron's normal process for making ATP for energy to fail. 2. The cell switches to anaerobic metabolism, producing lactic acid. 3. ATP-reliant ion transport pumps fail, causing the cell to become depolarized, allowing ions, including calcium (Ca+
+), to flow into the cell. 4. The ion pumps can no longer transport calcium out of the cell, and intracellular calcium levels get too high. 5. The presence of calcium triggers the release of the excitatory amino acid neurotransmitter glutamate. 6. Glutamate stimulates AMPA receptors and Ca++-permeable NMDA receptors, which open to allow more calcium
into cells. 7. Excess calcium entry overexcites cells and causes the generation of harmful chemicals like free radicals,
reactive oxygen species and calcium-dependent enzymes such as calpain, endonucleases, ATPases, and phospholipases in a process called excitotoxicity.[5][6] Calcium can also cause the release of more glutamate.
8. As the cell's membrane is broken down by phospholipases, it becomes more permeable, and more ions and harmful chemicals flow into the cell.
9. Mitochondria break down, releasing toxins and apoptotic factors into the cell. 10. The caspase-dependent apoptosis cascade is initiated, causing cells to "commit suicide." 11. If the cell dies through necrosis, it releases glutamate and toxic chemicals into the environment around it. Toxins
poison nearby neurons, and glutamate can overexcite them. 12. If and when the brain is reperfused, a number of factors lead to reperfusion injury. 13. An inflammatory response is mounted, and phagocytic cells engulf damaged but still viable tissue. 14. Harmful chemicals damage the blood brain barrier. 15. Cerebral edema (swelling of the brain) occurs due to leakage of large molecules like albumins from blood vessels
through the damaged blood brain barrier. These large molecules pull water into the brain tissue after them by osmosis. This "vasogenic edema" causes compression of and damage to brain tissue.
The fact that the ischemic cascade involves a number of steps has led doctors to suspect that neuroprotectants such as calcium channel blockers or glutamate antagonists could be produced to interrupt the cascade at a single one of the steps, blocking the downstream effects. Though initial trials for such neuroprotective drugs led many to be hopeful, until recently, human clinical trials with neuroprotectants such as NMDA receptor antagonists were unsuccessful.
Basic mechanism of excitotoxicity of stroke
It is widely believed that calcium entry into neurons significantly contributes to ischemia related toxicity remove Ca in experimental setting greatly
reduced hypoxic damage to neuron
Therapeutic strategy
Restore blood supply Minimizing Ca influx into cells Reducing free radical damage Promoting neural recovery
Tumor Radio-sensitivity
Taiwanese scientists studied the sensitization effect of Panax notoginseng extract and purified Saponin (Rb1) on the radiation response of an experimental tumor (KHT sarcoma) in comparison with its effects on a normal tissue (bone marrow) in mice
Tumor Radiosensitivity
Panax notoginseng extract at a concentration of 0.1-100 mg/kg produced an increase in tumor radiosensitivity.
Rb1 at a concentration 0.001 to 1 mg/kg produced an increase in tumor radiosensitivity, with maximum effect at 1 mg/kg.
The effect was maximal at 10 mg/kg and at 30 minutes after injection.
Higher doses of notoginseng (not Rb1) were toxic to the bone marrow stem cells
Further purified or synthetic versions are useful in cancer therapy.
Toxicity
Low Esophagitis from consuming tablets (drink
enough water) may occur Allergic reactions including dermatitis,
shock, purpura, blisters, or other idiosyncratic reactions

Chapter 7. Herbs that warm interior The warming interior herbs have the
function of warming interior, dispersing cold, warming kidney meridian and restoring collapse yang.
Properties: Pungent and sweet in flavor, hot and toxic in nature; it is related to the heart, kidney and spleen channels.
Functions: Recuperating depleted yang and rescuing the patient from collapse, restoring yang and supplementing fire as well as dispersing cold and relieving pain.
1. Cardiovascular system: Fu Zi and Sini Tang (Fu Zi, Gan Jiang, Gan Cao) have the function of recuperating depleted yang and warming heart yang. Heart yang deficiency is similar to heart failure, and arrhythmia of slow irregular pulse. Studies have proven that Fu Zi, Wu Tou, Gan Jiang and Rou Gui have obviously functioned on cardiovascular system which is related to Fu Zi's DMC (dl-demethlcoclaurine).
(1) Promote cardiac contratility Function: Fu Zi can strengthen cardiac contraction, increase heart beat, increase cardiac output and increase cardiac muscle oxygen consumption volume. The main ingredient of
strengthening heart function in Fu Zi is believed to be DMC (dl-demethlcoclaurine) which relates to Beta receptor. If the Beta receptor is blocked, increased cardiac contraction and heart rate will noticeably be decreased. DMC can shorten the period between A to H wave, and there is no change between H and H to V wave. It can increase the inotropic cardiac conductivity. The pure extract of Gan Jiang proves to have direct excitant function on heart.
(2) Promote cardiac frequency and inotropic conductivity: Fu Zi is proven to have treatment effect on treating of arrhythmia with slow heart beat type. Also DMC and Shen Fu Tang have similar function, too.
(3) Dilate vessels and improve circulation: Fu Zi and Rou Gui can dilate coronary vessels, increase coronary circulation, improving cardiac circulation, dilate brain vessels, and increase brain vessel circulation.
(4) Anti-shock function: Collapse syndrome and minute pulse to almost no pulse condition are similar to shock in western medicine. Fu Zi, Sini Tang, Sheng Fu Tang can elevate arterial pressure to prolong animal's life due to hypovolemic shock (blood loss), septic shock (infection with endotoxin),
cardiogenic shock (myocardial infarct). And, it provides protection on shock due to lack of oxygen or narrowing the vessels.
2. Digestive function: Rou Gui and Wu Ju Yu are warm and pungent which benefits stomach. Jiang (ginger)'s aromatic and acrid function can stimulate oral and intestine membrane and improve local circulation which leads to increase stomach secretion, enzyme activity, increase digestion, increase appetite and disperse digestive stagnation. Wu Ju Yu and Gan Jiang also can stop vomiting.
3. CNS function: Fu Zi, Wu Tou, Hwa Jiao, Hu Jiao, Gan Jiang, Rou Gui can relieve pain at different level. Fu Zi, Wu Tou , Hwa Jiao have analgesic function. Some warm interior herbs also have tranquilizing function. Sini Tang can promote sympathetic nerve to promote heat and disperse cold.
4. Anti-infection, immune function : Fu Zi, Xi Sin can reduce inflammation due to enzyme, PE2, etc. in the animal testing. Fu Zi can promote immunity by increasing IgM or IgG.
Fu Zi (Prepared Aconite Root) Two types: It is from the root of Wu Tou.
There are two types: Chuan Wu and Cao Wu. Properties: Pungent and sweet in flavor,
hot and toxic in nature, it is related to the heart, kidney and spleen channels.It is the root of Chuan Wu and Cao Wu.
Modern Researches: This herb contains aconitine, hypaconitine, talastisamine, chuanwu base A, chuanwu base A, racemic norcoclaurine, coryneine, etc.
Monkshood root and its decoction have an obvious cardiotonic effect and prepared sliced monkshood root has a more powerful cardiotonic effect. The longer monkshood root is decocted, the more remarkable are its cardiotonic effects and the lower its toxicity. Its
cardiotonic effects are closely related to the racemic norcoclaurine contained therein. It has obvious anti-inflammatory effects on formol and protein arthritis. Both the hypaconitine and aconine that it contains have tranquilizing and analgesic effects. It can resist myocardial ischemia and hypoxia, stimulate the pituitary adrenocortical system and promote blood coagulation.
Functions: 1. Cardiac vascular system function: (1)Strength heart system (2)Antiarrhythmia (3)Dilate vessels, lower blood pressure (dl-
demethylcoclaurine, higenamine), (4)increase blood pressure (coryneine
chroiole and salsolinol, SAL) (5)Protect heart muscle, promote enduring
time of lacking oxygen.
(6) Anti-shock 2. CNS system function: (1) Anti cold (2) Relieve pain (3) Analgesia 3. Anti-infection, increase immunity: (1)Anti-infection (2)Increase immune function 4. Others: (1) Digestive function (2) Increase Beta receptor, cAMP system reaction
(3)Increase KPTT and PCT time ( Fu Zi's activating blood function).
Indications: 1. Shock 2. Cardiac disorder (arrhythmia) 3. Arthritis, joint pain, lumbar pain, etc. Cautions: Being pungent, hot, dry and drastic, this
drug should be avoided by anyone with hyperactivity of yang due to yin deficiency or by pregnant women. It is against pinellia tuber,
Mongolian snakegourd (Fructus Trichosanthis), fritillary bulb (Bulbus Fritillariae Thunbergii), Japanese ampelopsis (Radix Ampelopsis) and hyacinth bletilla tuber (Rhizoma Bletillae). Being toxic, it should be blast-fried for oral administration. Any excessive oral administration or any improper blast-frying or decocting way may lead to poisoning.
